There is more than one way to raise a house. 

Many of the mobile homes, Creole cottages, and other dwellings that have been flagged for flood risk along Louisiana’s low-lying coastline can be separated from their foundations and slowly raised into the sky on hydraulic jacks. While a home is held aloft by temporary support beams, a new, elevated floor is built underneath or the foundation extended upward—think of the pilings you might see supporting a beach house.
